SECONDARY OR STORAGE BATTERY.

Application led November 29, 1912.

T0 all whom 'it may concern.' Be it known that I, BRUCE. FORD, a citizen of the United States, residing at the city `of Philadelphia, in the county of Philadel- -mize space and increase durability.

Other objects'of the invention will appear from the following description which will be made in connection with the accompanying drawings in which are illustrated embodiments selected from other embodiments for the purpose of description.

In the drawings Figure l, is a sectional View of a storage battery cell embodying features of the'invention. Fig. 2, is a sectional view taken on the line 2 2, of Fig. 1. Fig. 3, is a topor plan view of a number of cells electrically connected together. Fig. 4, is a side view of a number of cells electrically connected together, and Figs. 5 and are respectively a transverse section illustrating a modification and a section on the line 6 6, of Fig. 5.

There is a sectional conducting container, the sections l and 2, of which are insulated from each other. The sections l and 2, of the Vcontainer may consist of lead alloy or other appropriate material having or provided with the necessary conductivity. The sections are connected together but are insulated from each other.

3, is insulating material, as hard rubber.

4, is a metal band which may be crimpedto place and which serves to connect the sections l and 2, and the insulating material in such a way that the parts are secured t0- gether while at the same time the sections 1 and 2, are insulated from each other. The electrodes or plates 5, of one sign are mechanically and electrically connected to the section 2, and electrodes 6, of the opposite sign are mechanically and electrically connected with the section l. The connections between the electrodes and the sections can be made by burning, puddling, or in any convenient way and it provides a good electhe section 2,

trical path. Burning is a method of making joints by melting the metal of the two por.

tions to be joined into one union. Paddling involves this operation plusthe use of additional metal.

Separator-s 7, are shown between the plates, and the insulation 3, is extended upward as at 8, to form ay support for the plates. insulating rods 9, are shown as rest--l ing upon one set of .plates near their points of attachment to the container and passing through eyes in the'other set of plates so as to support or help support the latter. These are matters which mav or may not be used as required.

The container holds t-he necessary electrolyte and it may be provided with a filling opening and vented closure l0.

ll, is a box or tray in which several of the described containers and their contents are arranged with the sections thereof of opposite sign in contact with each other so as to connect up the'cells and provide terminals at the ends of the box or tray.

12,are blocks that may be employed between the containers in the bottom of the box, and 13, are wedges by means of which the containers can be held in proper contact -with each other and firmly in the box. The box of course is of insulating material or at any rate the containers are insulated from it.

In the modification shown in Figs. 5 and G, the sections lEl and 2, are divided horizontally instead of vertically and they are insulated b v the insulation 3a. The parts are properly secured together by bolts 4, suitably bushed with insulated material. rlhe plates 5, are shown as provided with lugs ll, by which they are connected with 7, are separators.

It will be obvious that modifications may be made in details so that I do not desire to limit my invention to such matters, but

Vhat I claim is:

1. The combination of sections of containers of opposite sign provided with flanges at their meeting edges, insulating material between and around saidflanges, and a metal band arranged around the container and having crimped connection with the insulating material and across the flanges.

2. The combination of sections of' containers of opposite sign provided with flanges at their meeting edges, insulating material bebetween the flanges and the fastening means,

substantially as described.

In testimony whereof I have hereunto signed my name.

BRUCE FORD. Witnesses:
